I wonder if, that even though it's a functioning church, especially due to it's cultural heritage (especially as it's already designated a UNESCO World heritage site), that now there will be an argument for much more funding in the future as it is a heritage building. It's not "just" a religious building. I know someone with a masters in museum policies, and she said, it's pretty much the norm, that cultural treasures are taken for granted, and no one wants to pay for them. Until it's at risk or lost. Then everyone cares.
I hope this is a lesson for governments the world over on the importance of adequately funding for the care and preservation of cultural landmarks like this. They really are a part of the cultural psyche of a place, and that is not even considering any scientific value. In this particular case, lets not forget the tourism value.
